Physics

Imagine that you have obtained spectra for several galaxies andhave measured the observed wavelength of a hydrogen emission linethat has a rest wavelength of 656.3 nanometers. Here are yourresults:

Galaxy 1: Observed wavelength of hydrogen line is 658.7nanometers

Galaxy 2: Observed wavelength of hydrogen line is 664.2nanometers.

Galaxy 3: Observed wavelength of hydrogen line is 683.6nanometers.

Part D: Estimate the distance to each galaxyfrom Hubble's law. Assume that H0=22km/s/Mly.

Express your answers using two significant figures.Enter your answers numerically separated by commas.

(dgalaxy1, dgalaxy2, dgalaxy3 = *Answer*Mly)
